QUESTION
I don't have much experience with Java nor with BPMN but m****y goal is to create a code that parse a .bpmn file deducing some information from it.
I don't need to execute the processes, I just need to infer some informations such as:
- which are the participant;
- what participant executes a specific task;
- which tasks follow a given task;
I've tried to look into the main technologies such as: Camunda, Flowable and jBPM; but to me they all seem to target the execution of processes rather than a merely syntactic analysis (which I think is what I need).
I'm now thinking of creating a code that parse the XML of a BPMN diagram using technologies like DOM or SAX.
Does anyone have a suggestion on how I should approach my goal ??
...ANSWER
Answered 2022-Mar-30 at 08:13BPMN files usually are structured as XML. So you can do your own XML-Parsing using JAXP. I also use the SAXparser, find a little introduction here.
I read there are BPMN libraries for Java, too, but I haven't tried any of these jet. Here is a good stack link for this topic: Parsing BPMN file
Hope this helps for a start :)

QUESTION
We've been executing a JBPM decision tree in memory for our call center. This works great, but we'd really like to be able to render diagrams in our BusinessCentral instance. This means we have to add JPAWorkingMemoryDbLogger so it logs stuff out to the drools tables. We're not using kie-server to execute our JBPM, but executing it in the follow code.
What we're finding is that every process instance id is 1, whereas other things JBPM we execute via kie-server manage to get an incremented PID.
What do we need to change in the setup of the KieSession so it it increments the process instance id?

- Adding a startup property to the wildfly startscript

QUESTION
I am using JBoss (Red Hat) product jBPM and have taken the docker images of kie-server and drools-wb (i.e. drools workbench).
I have brought up my docker images successfully and am able to navigate to business central ([https://localhost:8080/business-central]).
I want to run decision services on my local development server.
But when I hit 'deploy' for my decision service I get a popup message
...ANSWER
Answered 2021-Oct-12 at 06:16Kie-server must calls the workbench rest API for automatic registration, at the time, the kie-server will tell workbench what is the deployment api address, and then workbench can calls the deployment api to 'deploy' rule jar.
About how to configure, you can refre to Kie-server dockerfile
In this file, you can see more configure item. There have three items is about your problem: KIE_SERVER_CONTROLLER, KIE_SERVER_LOCATION and KIE_MAVEN_REPO
KIE_SERVER_CONTROLLER identifies the API call prefix of the workbench, kie-server will use this address for registration to workbench at the start time.
KIE_SERVER_LOCATION identifies the API call prefix of the kie-server, workbench will use this address for deployment rule jar.
KIE_MAVEN_REPO is kie-server use to download the rule jar of deployment.
KIE_SERVER_CONTROLLER: http://workbench_external_ip_address:port /kie-wb/rest/controller KIE_SERVER_LOCATION: http://kie_external_ip_address:port /kie-server/services/rest/server KIE_MAVEN_REPO: http://workbench_external_ip_address:port /kie-wb/maven2
You also can look the document , get the more detail.
QUESTION
I tried userinfo.property based task notifications and it works fine. But I'm stuck in sending notifications with DB users. I’m getting the below error.
23:49:35,378 ERROR [org.jbpm.services.task.deadlines.notifications.impl.email.EmailNotificationListener] (EJB default - 1) Unable to send email notification due to null
It seems to be coming from below line.
org.jbpm.services.task.deadlines.notifications.impl.email.EmailNotificationListener.onNotification(EmailNotificationListener.java:122)
I guess the system cannot load the user info from the DB.

...ANSWER
Answered 2021-Sep-18 at 00:09Java does not have lists or dictionaries / maps as built-in data types, so it does not offer syntax or built-in operators for working with them. One can certainly perform transformations such as you describe, but it's a matter of opinion whether it can be done "easily". One way would be something like this:

Vulnerabilities
Install jbpm
You can use jbpm like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the jbpm component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
